Whey is an important protein derived from the milk of cows. Cow’s milk consists of about 80% casein and 20% whey, with the 20% whey split further into various types of whey. The human body, which develops muscles with proper nourishment, readily absorbs this natural protein. Bodybuilders have known for many years the benefits derived from whey protein supplements, while elaborate scientific research studies are now beginning to catch-up. As a result, many research studies show the benefits it offers. Including the muscle-building properties, many people use this protein to improve their immune function and weight control. It is also being used to manage cancer and HIV.
Types of whey protein
The growing demand for this product has led to the production of different types of products. However, people must be careful about the cheaper products – they might be kind to the pocket, but often fail to deliver all the benefits available in the protein. The 3 main types of this protein available are the CONCENTRATE, the ISOLATE and the HYDROLYSED.
· The CONCENTRATE
Whey Protein CONCENTRATE (WPC) is often used to describe any type of protein that is ultra-filtered to achieve 25%-85% protein content, after pasteurization. Hence, it has a high level of de-natured proteins, cholesterol, fat and lactose. Furthermore, it is usually much cheaper.
· The ISOLATE
Whey Protein ISOLATE (WPI) is a more pure substance that contains more than 90% whey. Furthermore, it has a lower level of de-natured proteins, cholesterol, fat and lactose compared with the CONCENTRATE.
· The HYDROLYSED
Whey Protein HYDROLYSED (WPH) requires an additional step in the process of manufacturing. It is an enzyme pre-digested protein, which makes it possible for the body to hydrolyze most of the proteins before it is actually absorbed in the body. Therefore, when you take this protein HYDROLYSATE supplements the body readily absorbs them because they require less digestion. As a result, peptides and amino acids are readily available for the body.
Furthermore, this type allows you to get a large increase of insulin, but less of glucose. Compared with the ISOLATE, HYDROLYSED Whey Protein generates 28% more insulin required for energizing the muscles. Insulin response is effective before and during training, with this protein aiding with the process of recovery and building muscles. Nevertheless, because this product contains less sugar and fat than WPI, it has the least appealing taste. Moreover, it is a difficult type of protein to work with.
